600mm MAIN ROTOR BLADES
INSTRUCTIONS
Warning: The blade root reinforcements must be glued to the main blades. Please inspect the blades for damage before
assembling them. Do not exceed 1700 RPM with the wood blades or failure may occur. Blades are considered consumable
items and should be discarded if there is any sign of damage.
❏ 1. Position the blade as shown above and test fi t the top
reinforcement on the blade.
❏ 2. Turn over the blade and test fi t the bottom reinforcement.
❏ 3. Once you have verifi ed everything fi ts properly, mix up
some 30-minute epoxy and apply it to the exposed wood on
the root of the blade. Install the top and bottom reinforcements
as shown above. Double check your work to verify the
reinforcements are installed properly. Install and tighten the
two 2.6mm screws into the reinforcements as shown.
❏ 4. Use a paper towel dampened with isopropyl alcohol to
remove the excess glue from the blade. Before the epoxy sets,
install the blades into the grips to clamp the reinforcements
down onto the blade. Once the epoxy has set, you can
proceed to use the blades.
BLADE BALANCING
Note: All main blades must be balanced before use. We
recommend using the Heli-Max Blade Balancer (HMXR4855).
❏ 1. Apply the two colored stripe decals to the tips of your
main rotor blades (for use in blade tracking later on).
❏ 2. Prepare the balancer for use by rotating the brass
adjustment dial until the bubble in the vial indicates level.
Make sure that the blade balancer does not move during
this process.
❏ 5. Position the second blade on the tray, with the mark
at the center. Add balancing or electrical tape to the lighter
end until the bubble indicates that both sides are level. The
C.G. of both blades is now matched. If the tape ends overlap,
make sure the overlapping end points to the trailing edge of
the blade.
❏ 6. Your Heli-Max Blade Balancer includes four sizes of
blade mounting plates and a nylon mounting bolt. Select
❏ 3. Place one blade onto the balancer with the leading
edge against the side with the level. Shift the blade on the
balancer until the bubble indicates level. The middle of the
black balancing tray is now at the C.G. of this blade. Mark this
position on the blade with a felt tip pen.
the mounting plate that best fi ts the holes in the blade grips.
Secure the mounting plate and two blades to the balancer
with the nylon mounting bolt.
❏ 7. Add tape to the C.G. of the lighter blade until the bubble
level indicates that the two blades balance. Using a different
❏ 4. Line up the ends of both blades. Transfer the mark you
made on the fi rst blade to the second blade.
